LEPTOSPERMUM (from leptos, slender, and 
sperma, a seed; seeds slender). Including Fabricia. 
Orp. Myrtacew. This genus comprises about twenty-five 
species of greenhouse or half-hardy shrubs, rarely small 
trees, mostly natives of Australia. Flowers 
white, sessile, or rarely shortly pedicellate, solitary, 
or two or three together, at the ends of short branch- 
lets, or in the axils of the leaves. Leaves alternate, 
small, rigid, entire, nerveless, or one or three-nerved. 
Leptospermums thrive in a compost of loam and peat, 
to which may be added a small quantity of sand and 
charcoal. Propagated by cuttings of young shoots, 
placed in sand, under a glass, during May; or by 
seeds, sown in gentle heat, during March. The species 
are not very generally cultivated.

L. s. juniperinum (Juniper-like). A narrow.leaved form, 
iowa ae with the type, except in the foliage. : 
LEPTOSYNE (from leptosein, slenderness; a name 
applicable to the original, but not to most of the species, 
except as to the leaves and their divisions). ORD. Com- 
posite. A genus (now included, by Bentham and Hooker, 
under Coreopsis, but regarded as distinct by Dr. Asa 
Gray) containing about seven species of New World 
annual or perennial, herbaceous or suffruticose, smooth 
and glabrous plants, with showy pedunculate heads—the 
ray and disk being both bright yellow—and pinnately 
divided or dissected leaves. They have the habit of 
Coreopsis (which they represent on the Western side of 
North America), “but mostly with pistillate rays, and 
always with a ring on the tube of the disk corollas, or 
at its juncture with the throat” (Gray). For culture, see 
Coreopsis. 
L. calliopsidea (Calliopsis-like). f- heads rather large and broad, 
with peduncles a span long. Autumn. l., lobes narrowly linear, 
sometimes incised. h. 1ft. to 2ft. California. Annual. (R. H. 
1873, 330, under name of Leptosyne maritima.) ; 
L. maritima (maritime). /l.-heads large; rays sixteen to twenty, 
lin. or more long; disk generally lin. in diameter. Autumn.

opsis maritima.)

LEPTOTES. Included under Tetramicra (which see). 
LESCHENAULTIA (named after L. T. Leschenault, 
1773-1826, a French botanist and traveller), Fi 
spelt Lechenaultia. ORD. Goodenoviee. A genus 
prising sixteen species of very ornamental greenhou 
herbs, under-shrubs, or shrubs, confined to Australia. 
Flowers blue, white, yellow, red, or greenish, either soli- 
tary and terminal or leaf-opposed, or several in compact, 
leafy, terminal corymbs; corolla oblique, the tube slit 
open to the base, or rarely closed, the lobes all or par- 
tially erect, and connivent or spreading. Leschenaultias 
are amongst the most beautiful and effective of green- - 
house hard-wooded plants. Their successful cultivation 
requires the most careful attention at all seasons, par- 
ticularly in regard to watering. They are propagated 
from cuttings, which should be taken, in spring or summer, 
from the points of shoots that are moderately firm, and 
inserted in well-drained pots of very sandy peat, under 
a shaded bell glass, in a little heat. Established plants 
will sometimes require a little stopping, to insure a 
symmetrical habit. This should be seen to so soon as 
flowering is over; and, if it is necessary, a few small 
stakes may be used for training or supporting the branches 
left. The soil used in potting or re-potting should con- 
sist of fibry peat and silver sand. It is very important 
that the stem of the plant should not be buried, or placed 
so as to be lower than the surrounding soil. A rather close 
frame will be best for a time, after the roots have been dis- 
turbed ; but a light, airy situation should be afforded at all 
other times. The plants should not be exposed in the open 
air to ripen their growth; this treatment is generally inju- 
rious, if not fatal to them, although it is beneficial to 
per tga cca a 1 but much stronger - 
growing nature. a light, sunny position, un 
is selected for their cultivation en ee, e ene 
and winter, ripening of the wood may fairly be expected, 
and the plants will be uninjured by alternate heavy rains 
and drying winds. Only soft water should be used for 
watering, and it should be judiciously administered at 
all times. L. biloba mojor is perhaps the finest blue- 
flowered hard-wooded shrub in cultivation, and L. formosa 
is an exceedingly handsome species. The species de- 
scribed below are those best known to cultivation.
